Show us a picture of the "local" power supply.

Well, generic **** power supplies (or local) provide 30~60% (sometimes more) of the rated wattage, that's the difference.

It depends on the "local" power supply and the "Branded" unit in question. Some brands, like Diablotek provide PSUs that are as much junk as the cheap stuff your local stockist probably palms off on unsuspecting purchasers.

Like the nice grey "700w" unit that is really an over-labeled 450w that goes out of spec at 451w and explodes messily at 650w and probably takes your computer with it.

On the other hand, some suppliers take a semi-decent unit, put their own labels on it, and sell it for a good price. A supplier near me provides units based on the same Sirfa platform that OCZ uses, and sells it for a good price.

Basically, if you have enough money to buy a trusted, branded PSU, then avoid the off-brand units like the plague.

The CM Extreme PSUs are meh. Medioocre units that IIRC are not 80 PLUS certified and are based on older designs with no APFC.

The difference is stability. You want a power supply that can provide a solid flow of power regardless of what load it's being put under.

Generally, cheap "local" units have an unstable flow of power, which gets considerably worse as load goes up. Also, when a cheap unit goes out it typically takes a few components with it. A quality power supply does not.

Even if you are not overclocking, a quality power supply is vital in order to have a rock solid system for many years.

I think you mean "unlike" Corsair. OCZ is mehhh but Corsair/Seasonic are One of THE BEST psu manufacturers. You are clearly confused.
